Herb-Infused Oils, The Secret To Levelling Up Every Dish

Herb-infused oils are culinary preparations where fresh or dried herbs are steeped or infused in a base oil, such as olive oil or grapeseed oil, to extract their flavours and aromas. These oils serve as a concentrated source of herbaceous essence, adding depth, complexity, and unique flavour profiles to dishes.

The popularity of herb-infused oils in the culinary arts stems from their ability to elevate ordinary dishes to extraordinary culinary experiences. They offer a simple yet effective way to infuse a burst of herbal goodness into various recipes, ranging from salads, marinades, and dressings to pasta sauces and roasted vegetables.

Using herb-infused oils in cooking provides numerous benefits. Firstly, they enhance the overall flavour profile of a dish, creating a harmonious blend of aromas and tastes. Secondly, they offer versatility, allowing chefs and home cooks to experiment with different combinations of herbs and oils, resulting in endless flavour possibilities. Lastly, herb-infused oils add an elegant touch to presentations, visually enhancing the appeal of a dish.

Selecting the Right Herbs

When selecting herbs for infusion, there is a wide array of options to consider. Some popular herbs for infusion include basil, rosemary, thyme, oregano, sage, cilantro, and mint. These herbs possess distinct flavours and aromas that can greatly enhance the oils they are infused in.

When it comes to selecting fresh herbs, there are a few considerations to keep in mind. Look for herbs that are vibrant in colour, with no signs of wilting or discoloration. They should have a strong aroma, indicating their freshness. opt for herbs that are pesticide-free and preferably organic, as they ensure a higher quality infusion

To create unique flavour profiles, you can experiment with combinations of herbs. For instance, combining basil and thyme creates a bright and aromatic infusion, perfect for salads and pasta dishes. Rosemary and garlic infusion adds a savoury and robust flavour, ideal for roasted vegetables and grilled meats. Consider the compatibility of different herbs and experiment with various combinations to discover your preferred flavours. Remember to balance the intensity of the herbs to avoid overpowering the oil with one particular flavour

Choosing the Base Oil

When choosing a base oil for herb infusion, several options are suitable for creating flavourful infusions. Common choices include olive oil, grapeseed oil, sunflower oil, avocado oil, and canola oil.

Each base oil possesses its own flavour profile and characteristics. Olive oil, for example, offers a fruity and slightly peppery taste, which pairs well with a variety of herbs. Grapeseed oil has a neutral flavour, allowing the herb flavours to shine through. Sunflower oil has a mild flavour and is an affordable option for infusions. Avocado oil has a rich, buttery taste that complements robust herbs. Canola oil, with its mild flavour, serves as a versatile base for infusions.

When selecting a base oil, consider factors such as the intended use, the desired flavour outcome, and the oil's heat resistance. Some oils are better suited for cold infusions, while others can withstand heat for heat infusions. Additionally, consider the quality and freshness of the oil to ensure a superior final product.

Infusing Techniques

Infusing oils with herbs can be achieved through two primary methods: cold infusion and heat infusion. 

The Cold Infusion Method

This method involves placing fresh or dried herbs of your choice, such as rosemary, thyme, or basil, in a clean glass jar. Next, pour a neutral oil like olive or grapeseed oil over the herbs, ensuring they are fully submerged. Seal the jar tightly and allow it to sit in a cool, dark location for about 1 to 2 weeks. During this time, the flavours of the herbs naturally infuse into the oil. Once the infusion period is complete, strain the oil to remove the herbs, and transfer the infused oil to a clean bottle for storage.

Heat Infusion Method

This method involves combining the herbs and oil in a heatproof container or saucepan. Gently heat the mixture over low heat for 1 to 2 hours, stirring occasionally. The heat helps to expedite the infusion process, allowing the flavours of the herbs to infuse into the oil more quickly. After heating, let the mixture cool to room temperature. Then, strain the oil to remove the herbs, and transfer the infused oil to a clean bottle for storage.

Storing and Preserving Herb-Infused Oils

When it comes to storing and preserving your herb-infused oils, proper techniques are essential to maintain their quality and freshness. Use dark, airtight glass bottles or containers to protect the oils from light and air exposure, which can cause oxidation and spoilage. Ensure that the containers are thoroughly cleaned and dried before transferring the oils. 

The shelf life of herb-infused oils can vary, but they generally last between 2 to 6 months when stored correctly. Factors such as the type of oil used, the freshness of the herbs, and the presence of additional ingredients can affect longevity. Keep the oils in a cool, dark place away from direct sunlight and heat sources to extend their shelf life.

It's crucial to be aware of signs of spoilage, such as off odours, mould growth, or cloudiness in the oil. If you notice any of these signs, it's best to discard the oil to avoid the risk of foodborne illnesses. Regularly check the oils for any changes and trust your senses when determining their quality.

By following proper storage techniques and recognising signs of spoilage, you can ensure that your herb-infused oils remain flavourful and safe to use.

Tips for Enhancing Flavors

Incorporating additional ingredients: Add depth and complexity to your herb-infused oils by including complementary ingredients. For example, infuse garlic cloves along with your herbs for a savoury twist. Citrus zest can provide a refreshing and zesty note, while chili flakes add a touch of heat.

Balancing flavours: Achieve a harmonious balance of flavours by adjusting the intensity of the herbs and other ingredients. Start with smaller quantities and taste as you go, gradually adding more if needed. Avoid overpowering the oil with one dominant flavour and aim for a well-rounded profile.

Experiment with unique herb combinations: Don't be afraid to venture beyond traditional combinations. Explore unique herb pairings to create intriguing flavours. For instance, try combining lavender and thyme for a floral and earthy infusion or mix coriander and lemongrass for a vibrant and citrusy twist.

Food Pairings and Recommendations

Herb-infused oils can elevate various types of food to new heights. Here are some suggested pairings and recommendations:

Salads: Drizzle basil-infused oil over caprese salad or mix a lemon-infused oil into a citrusy vinaigrette for green salads.

Pasta dishes: Toss rosemary-infused oil with roasted vegetable pasta or finish a creamy carbonara with a drizzle of garlic-infused oil.

Grilled meats: Brush thyme-infused oil onto grilled chicken or marinate lamb chops with a mint-infused oil for a burst of freshness.

Roasted vegetables: Use a garlic-infused oil to coat root vegetables before roasting, or add a touch of chili-infused oil for a spicy kick to roasted cauliflower.

Bread and dips: Serve a bowl of herb-infused oil alongside freshly baked bread, or mix a basil-infused oil into hummus for an herbaceous twist.

Recipe for Thyme Infused Olive Oil


1 cup of high-quality olive oil

1/4 cup of fresh thyme sprigs (washed and thoroughly dried)


Remove the leaves from the thyme sprigs, discarding the woody stems. You can do this by running your fingers along the stem in the opposite direction of growth.

In a small saucepan, gently heat the olive oil over low heat until it reaches a warm temperature. Be careful not to let it simmer or boil.

Once the oil is warmed, add the thyme leaves to the saucepan. Stir gently to ensure the thyme is evenly distributed.

Allow the thyme to infuse in the warm oil for about 30 minutes to 1 hour. This allows the flavours of the thyme to meld with the oil.

After the infusion time, place a fine-mesh sieve or cheesecloth over a clean glass jar or bottle. Carefully pour the infused oil through the sieve, allowing the oil to strain into the container. This will remove any thyme leaves or particles.

Storage: Seal the jar or bottle tightly and store it in a cool, dark place to preserve the flavour and quality.
